Abstract
The proportioner (10) has a variable speed controlled DC motor (12) having a gearbox (14) and crankshaft (16) at either end which are connected to reciprocating piston pumps (18). The outputs (18 a) of the two pumps (18) are fed to a manifold (22) where the pressure of each output is measured. The user sets a setpoint pressure (e.g. 1000 psi) and the controller (26) then compares the pressures of the two components and controls the higher of the two relative to the setpoint. Ratio assurance is monitored by continuing to look at both output pressures. If one side falls below a predetermined percentage of the setpoint (50% in the preferred embodiment), an alarm may be raised or operation stopped.
Description
- This application claims the benefit of U.S. application Ser. No. 60/423,342, filed Nov. 1, 2002.
- Plural component proportioners for the mixing of materials such as polyureas and other foams are well known. Such devices have traditionally been simple mechanical proportioners or else complicated and heavy hydraulic powered units. While electrically operated units such as that shown in U.S. Pat. No. 3,196,802 have been used to proportion plural component materials, such are not designed for fast setting materials of the type mentioned which require precise control of both ratio and pressure.
- It is therefore an object of this invention to provide a proportioner which is electrically powered, can be easily manufactured and serviced is easily transported and capable of precise metering of the two components.
- Towards this end, the proportioner has a variable speed controlled DC motor having a gearbox and crankshaft at either end which are connected to reciprocating piston pumps. Such motors, gearboxes and cranks are well known for use in electrically powered airless paint sprayers such as those sold by the assignee of the instant invention under the trademark ULTRA. The outputs of the two pumps are fed to a manifold where the pressure of each output is measured. The user sets a setpoint pressure (e.g. 1000 psi) and the controller then compares the pressures of the first and second components (typically designated as the catalyst or A component and the resin or B component) and controls the higher of the two relative to the setpoint. Most materials today are designed for 1:1 ratios, that is, equal amounts of each component. Because of variations in viscosity and temperature, even though equal amounts of each component will be pumped (for mixing at the spray gun or other applicator) the pressure might be higher on one side or the other. Thus the controller continually compares the pressures and regulates the higher one to the setpoint.
- Ratio assurance is monitored by continuing to look at both output pressures. If one side falls below a predetermined percentage of the setpoint (50% in the preferred embodiment), an alarm may be raised or operation stopped. Of course this threshold percentage may be varied.
- These and other objects and advantages of the invention will appear more fuilly from the following description made in conjunction with the accompanying drawings wherein like reference characters refer to the same or similar parts throughout the several views.
-
FIG. 1 is an isometric view of the front of the proportioner of the instant invention. -
FIG. 2 is an isometric view of the rear of the proportioner of the instant invention. - The proportioner of the instant invention, generally designated 10, is shown in
FIGS. 1 and 2 . Towards this end, theproportioner 10 has a variable speed controlledDC motor 12 having agearbox 14 andcrankshaft 16 at either end which are connected to reciprocatingpiston pumps 18. Such motors, gearboxes and cranks are well known for use in electrically powered airless paint sprayers such as those sold by the assignee of the instant invention under the trademark ULTRA. Theoutputs 18 a of the twopumps 18 are fed toheaters 20 and thence to amanifold 22 where the pressure of each output is measured bypressure sensors 24. - The user sets a setpoint pressure (e.g. 1000 psi) and the
controller 26 then compares the pressures of the two components and controls the higher of the two relative to the setpoint. The DC motor control is of the type shown in U.S. Pat. No. 4,397,610, the contents of which are hereby incorporated by record. - Most materials today are designed for 1:1 ratios, that is, equal amounts of each component. Because of variations in viscosity and temperature, even though equal amounts of each component will be pumped (for mixing at the spray gun or other applicator) the pressure might be higher on one side or the other. Thus the
controller 26 continually compares the pressures and regulates the higher one to the setpoint. - Ratio assurance is monitored by continuing to look at both output pressures. If one side falls below a predetermined percentage of the setpoint (50% in the preferred embodiment), an alarm may be raised or operation stopped. Of course this threshold percentage may be varied.
- Ratio assurance is monitored by continuing to look at both output pressures. If one side falls below a predetermined percentage of the setpoint (50% in the preferred embodiment), an alarm may be raised or operation stopped.
- It is contemplated that various changes and modifications may be made to the proportioner without departing from the spirit and scope of the invention as defined by the following claims.
